How to Lose Up to 20% of Your Body Weight Without Traditional Weight Loss Surgery
By Dr. Alexander Shapsis, MD, FACS — EndoSlim Clinic NY
Losing a meaningful amount of weight has traditionally been associated with bariatric surgery, abdominal incisions, removal of part of the stomach, and a lengthy recovery.
Today, eligible patients may have another option.
A minimally invasive endoscopic procedure can reduce the functional size of the stomach from the inside, helping patients feel full sooner, eat smaller portions, and develop healthier long-term eating habits.
With appropriate nutrition, lifestyle changes, and medical follow-up, patients may lose approximately 15–20% of their total body weight. Individual results vary, and no specific amount of weight loss can be guaranteed.
The procedure is performed through the mouth without external incisions and is typically completed in less than 90 minutes.
Quick Facts

- ✨ Usually completed in approximately 60–90 minutes
- ✨Designed to help patients feel full sooner

- ✨ Patients may lose approximately 15–20% of total body weight
- ✨ Long-term results depend on nutrition, follow-up, activity, and consistency
Watch How the Procedure Is Performed
The video below shows how the stomach can be reshaped from the inside without traditional abdominal surgery.
During the procedure, a flexible endoscope is carefully passed through the mouth and into the stomach. A specialized endoscopic suturing system is then used to place internal stitches that fold and reshape the stomach.
- No external incisions are required.
- No part of the stomach is removed.
The result is a smaller, sleeve-shaped stomach that holds less food and helps patients feel satisfied with smaller meals.
What Is the Incision-Free Weight Loss Procedure?
The procedure is called Endoscopic Sleeve Gastroplasty, commonly known as ESG.
ESG is a minimally invasive endoscopic weight loss procedure that reduces the stomach’s functional volume using internal sutures.
Unlike surgical sleeve gastrectomy, ESG does not require the removal of stomach tissue. Instead, the stomach is folded inward and reshaped from the inside.
This smaller stomach capacity can help patients:
- Feel full after eating less food
- Reduce portion sizes
- Slow down during meals
- Improve appetite control
- Build healthier long-term eating habits

How Can a Smaller Stomach Support Weight Loss?
Weight loss does not happen simply because the stomach is smaller.
The procedure creates a physical tool that can make portion control easier. Patients may feel satisfied after eating less food and remain full for longer periods.
This can support a gradual reduction in daily calorie intake without requiring the removal of part of the stomach.
However, ESG is not a replacement for healthy habits.
The procedure works best when it is combined with nutrition guidance, regular medical follow-up, physical activity, and consistent lifestyle changes.

How Much Weight Could 20% Be?
When patients hear “20% of your body weight,” they often wonder what that means in real life.
Here are a few examples based on total body weight:
| Starting Weight | 15% Weight Loss | 20% Weight Loss |
|---|---|---|
| 200 lbs | 30 lbs | 40 lbs |
| 225 lbs | 34 lbs | 45 lbs |
| 250 lbs | 38 lbs | 50 lbs |
| 275 lbs | 41 lbs | 55 lbs |
| 300 lbs | 45 lbs | 60 lbs |
These examples are for illustration only. Every patient’s journey is different, and weight loss depends on nutrition, activity level, medical conditions, and long-term follow-up.

- Adults living with obesity or excess weight
- Patients who prefer a minimally invasive option

Benefits Compared with Traditional Weight Loss Surgery
| Endoscopic Procedure | Traditional Bariatric Surgery |
|---|---|
| No external incisions | Requires abdominal incisions |
| No stomach removal | Part of the stomach is permanently removed |
| Performed through the mouth | Laparoscopic surgery |
| Usually 60–90 minutes | Typically longer operative time |
| Faster recovery for many patients | Longer recovery period |
| Minimally invasive | Major surgical procedure |
Although the procedure is less invasive than bariatric surgery, it still requires commitment to healthy eating habits and regular follow-up for long-term success.
What Is Recovery Like?
One of the reasons many patients choose this minimally invasive procedure is the recovery experience.
Most patients return home the same day. Temporary nausea, stomach cramping, bloating, and fatigue are common during the first few days as the stomach adapts to its new shape.
These symptoms are expected and are usually managed with medication, hydration, and a structured dietary progression.
Most patients begin feeling significantly better within several days and gradually transition to soft foods before returning to a long-term healthy eating plan.
